I have a very specific project that I'd like to use the Recorder II for and would like to know the power usage before I order one. I saw on the specs AC voltage, but figure that this is an AC adapter, and not the unit itself. Any idea on the V*A=W? Volts, Amps and Watts in DC? Does it depend on the memory card? If so, then what is the AC adapter sized for?

Long story short, I'm trying to size the thing for a battery (portable power supply) capable of filling up a 4GB CF microdrive.

I want to use it for a helmet-cam recorder.

Thanks,
Ross

Assuming it's similar to the Recorder 1, then it works at 5VDC and draws less than an 1A. In otherwords, just about any NICAD, NIMH, alkaline, or gel cell pack can power it no problem for a few hours. I'd recommend a voltage regulator chip hooked in with the battery to be on the safe side.

This is a question that could be answered with about 15 second of time looking at the power adaptor ("wall wart"). Those things have the power output printed on them, which is all Ross is asking for. Are there any Recorder 2 owners out there who could take a look at theirs?

Output on wall wart:

5V DC
1.5A
8W Max
+ on center, - on outer ring

I haven't actually tested this, but my guess is that power draw is probably about 3W or so when recording to microdrive. There is considerable discussion about power consumption in the context of charging via USB on the google groups discussion.

Let me know how that works out. I had a similar thought for an in-car camera in a race car. Need something fairly small and with no moving parts.

Be careful using the neuros/microdrive with a helmet cam.
We corrupted our microdrive.
Go with a 2GB CF.
By the way, a cheap 5 volt regulator and a 7.2 volt RC battery works like a charm. We made our own system.
5 volt regulator here: http://www.eaelec.com/12to6.htm#5volt
Weatherproof cam/audio that runs 3 hours on a 9 volt battery.
We used our neuros at -17C in the snow with an all weather headcam (snowboarding).
Works great!

Ex-Navy,

I'm interested in the system that powers the recorder with a standard 9V battery. Are you selling them?

Thanks
